【技术实现步骤摘要】
一种自动浇注机用四点托盘整体浮动式称重机构
本技术属于铸造领域,涉及自动浇注机,尤其是一种自动浇注机用四点托盘整体浮动式称重机构。
技术介绍
自动化浇注实现浇注过程的自动化就需对浇注重量进行准确的称量。常见的浇注机称重方式采用四点称重,来实现对浇注重量的测量。这种称重方式的缺点在于:称重方式采用点接触,通过称重传感器信号对浇注重量进行测量,四点称重的稳定性较差。为实现点接触需通过滚珠丝杠提升、导轨导向来实现对浇注重量的测量,滚珠丝杠和直线导轨直接影响称重的精度和响应的时间,实用过程中丝杠和导轨的磨损影响称重。称重精度较低,响应时间较长。
技术实现思路
本技术所要解决的问题在于克服现有技术的不足,提供一种测量精度高和响应时间短的自动浇注机用四点托盘整体浮动式称重机构。为实现上述目的,本技术采用的技术方案为:一种自动浇注机用四点托盘整体浮动式称重机构,包括称重机架,所述的称重机架安装在横向行走大车和纵向提升机构之间,所述的称重机架的四角各固定设置称重安装面,所述的称重安装面下方设有托盘,所述的托盘与称重安装面之间固定设有橡胶缓冲垫,在所述的托盘下方设有称重传感器;称重机架、橡胶缓冲垫、托盘、称重传感器构成四点托盘整体浮动式称重机构。本技术与现有技术相比有显著的优点和有意效果:本称重机构利用了四点浮动整体称重,对安装于称重机架上的所有机构和浇注液进行称重,去除了机械结构对称重精度和响应时间的影响,称重重心只需保证在称重传感器的四点之间就可以准确快速的进行称重,降低了提升机构的纵向移动对称重精度和响应时间的影响,称重机架和称重传感器之间安装橡胶缓冲垫,减轻了因设备震动 ...
